Apple gave no details about what changes or fixes come in the latest build. But any changes are likely to be minor, as it is not labeled as a full fledged "Preview 3." People familiar with the latest build say it is dubbed version 11A444d.

Preview 2 of Lion was released to developers in late March, marking the second major developer preview of its forthcoming operating system. Developers can download the pre-release software from the Mac App Store after requesting a redemption code.

Earlier this month, Apple issued its first update for Lion Preview 2. Like Friday's update, it did not come with a list of changes or fixes.

Apple will highlight more features of Lion at its forthcoming Worldwide Developers Conference, to be held June 6 through 10 in San Francisco, Calif. There, the company has promised to "unveil the future of iOS and Mac OS." Lion is set for release this summer.
